Authentication problem with Google Account: Waitlist invite email mismatch prevents login

Description

I'm unable to login to Claude Code because my waitlist invite was sent to a slightly different email address than my Google account email.

Details

• My Google account email: example.user@gmail.com (with a dot)
• Email that received the waitlist invite: exampleuser@gmail.com (without the dot)

When attempting to authenticate with Claude Code, the system doesn't recognize my Google account as having access, presumably because the waitlist approval is tied to the email without the dot - even though Google doesn't differentiate.

Steps to Reproduce

1. Install Claude Code (npm install -g @anthropic-ai/claude-code)
2. Run claude in terminal
3. Authentication flow opens in browser
4. Sign in with Google account (the one with the dot)
5. Authentication fails - not recognized as having waitlist access

Expected Behavior

The system should recognize that example.user@gmail.com and exampleuser@gmail.com are effectively the same Gmail address (Google treats dots in Gmail addresses as identical) and allow me to authenticate.
